I applied through an employee referral. The process took 1 day. I interviewed at Qualcomm in Jan 2010
Interview
This was a thorough interview, with 8 or 9 people interviewing me over a day lasting from about 10:00 am to 4:00 pm.

Interview questions [1]
Question 1
How would you create a linked list and then reverse its members?
